At this time (July 11, 2005) we don't carry any upgrades for the valve.

If the valve lock screws have stripped out the body of the valve or the threads for the braided hose or vertical adapter have stripped then you will need to get this complete assembly. The Valve Body 98-25N is no longer available.

If you can hear a continuous leak from the barrel or breach, it is commonly due to a bad oring, seat, or seal inside the valve.

However Tippmann does not recommend disassembly of the valve on your own. It's difficult to do and it is easy to damage more parts, which will require a complete valve anyway.
